from the following ingredients, combined in substantially theproportions stated, namely:

Phenol (carbolic acid), crude lquart.

Aqua ammonia, concentrated 1 pint. Oil of cedar 2ounces. Sulfate of zinclounce. Sugar of lead 2 ounces. Oil of sassafras fl ounces. Oil of spikeounces. Corrosive sublimate 20 grains.

The ingredients are to be thoroughly commingled, preferably by stirringor a itation. The sulfate of zinc and acetate of lead (or sugar of lead)when mixed in solution form respectively acetate of zinc and sulfate oflead, and the latter will be precipitated. The zinc acetate will at oncereact with the ammonia water and will all be converted into zinchydroxid, which, like the lead sulfate, is insoluble. The corrosivesublimate also will be acted on by the ammonia resulting in theformation of mercuric ammo nium chlorid. An excess of ammonia water willremain. The anhydrous salts of-thev lead acetate and zinc sulfate arereferred to in the formula above, and are in combining or substantiallycombining proportions, and
